How to parse a VARCHAR passed to a stored procedure in SQL Server?
Another alternative is to use "indirection" (as I've always called it)
Then you can do this...
proc Criar Sp_ReturnPrdoucts
@BrandIds varchar(500) = '6,7,8'
E
START
if (isnumeric(replace(@BrandIds,',',''))=1)
Start
exec('SELECCIONE * DE tbl_Products como púnase a tbl_Brands b en p.ProductBrandId=b.BrandId DONDE b.BrandId IN ('+@BrandIds+')')
fin
THE END
In this way, the select statement is constructed as a string and then executed.
Now I've added validation to make sure the string passed is purely numeric (after removing all commas).
Stored procedure to parse a string
One possible solution is to use XML
DECLARE @text VARCHAR(1000)
,@xml-xmlSELECT @text = 'City=Hyderabad | Cellphone=48629387429 | role=user | Name = Praveen'
SELECT @text = REPLACE(@text,'|',''')
,@text = REPLACE(@text,'=','="')
,@text = '<line' + @text + '"/>'
SELECT @xml = CAST(@text AS XML)
select
line.col.value('@Name[1]', 'varchar(100)') AS-Name
,line.col.value('@City[1]', 'varchar(100)') AS City
,line.col.value('@Mobile[1]', 'varchar(100)') AS Móvel
,line.col.value('@Role[1]', 'varchar(100)') AS-Role
FROM @xml.nodes('/fila') AS line(col)

(Video) Stored procedures in sql server Part 18How to convert varchar to integer in SQL Server stored procedure?
The number table solution I posted for this question is the most efficient solution. Print bullets before each sentence + newline after each sentence Insert SQL code once you get home
to edit
The basic unit of work is the online table-valued function. You may have heard of TVF and how they are taking over SQL Server, but this belongs to them.multiple statementtypes Inline lines are good as the optimizer can understand them and doesn't make terrible plans.
dbo.StringSplitreturns a single-column table (varchar) in which values are partitioned based on the specified delimiter. You can reduce the required lines of code (derived tables from L0 to L5) if you already have tables of numbers or a fast number generator in your data. I suppose not. The technique of using a numeric table to split data is not mine, but I trust the SQL luminaries who did the analysis.
They asked for a lawsuit so I gave itdbo.StringSplitToIntsto comply, but all it does is call the TVF with the correct parameters. You can extract the select statement and align it or wherever you need it.

How to pass a list of strings as parameters in a stored procedure in SQL?
You must use table-valued parameters
Define the new type as follows
CREATE TYPE Prod_Code AS TABLE(ProductCode varchar);Then use that type in your stored procedure
create procedure [dbo].[aggregation_proc]
@Prod_Code Prod_Code AULA SOLO,
@Prod_Desc varchar (30)
e
......Now populate the table before calling the stored procedure

Passing a varchar full of comma separated values to a SQL Server IN function
Do not use a loop function to split a string!, my function below splits a string very quickly, with no loops!
Before using my function you need to set up a "help table", you only need to do this once per database:
CREATE TABLE Numbers
(int number NOT NULL,
RESTRICCIÓN PK_Numbers PRIMARY KEY CLUSTERED (Número ASC) CON (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARIO]
) IN [PRIMARY]
DECLARE @x int
DEFINE @x=0
DURING @x<8000
START
DEFINE @x=@x+1
INSERT VALUES INTO NUMBERS (@x)
THE END
